Figure 35: Examples of the Bargraph "Below, Within and Above Tolerance"
NOTE: (bargraph for filling and emptying modes)
For modes other than check-weighing, the bars will be on only while the setpoints are on and during the "Done" at the
end of a fill.
The bar weights will be calculated similar to the check-weigh modes of operation stated above for filling, batching,
etc., except that the percentage will be based on the actual target, rather than the low-limit value (see the equation
below). The operation for emptying (and the emptying portion of 'both') will be the same except that the weight will be
going negative while the left side bars are turning off.
Although the setpoint annunciators are not motion-inhibited, the setpoint relay outputs will not activate until
a no-motion condition exists.
Percentage Check-Weighing
This feature is commonly used in check-weigh applications. After a target weight is entered, upper and lower
tolerances are entered as a percentage of the target. Over and under tolerance values are automatically calculated
